Road Notice (3/22/2022): Interstate 81 Lane Widening Construction from Exit 137 to 141

VDOT traffic alert

A $179 million design-build project to widen both directions of I-81 between mile markers 136.6 and 141.8 from two to three lanes is set to begin. Starting in February and continuing into the early summer, work will be performed on the inside and outside shoulders along a five mile section of both northbound and southbound Interstate 81 in Roanoke County and the City of Salem. The shoulders will be built up before a barrier wall can be installed for road crews to work behind. Barrier wall will be installed along the shoulders in the spring and summer. Two lanes of I-81 traffic in each direction will remain open during the project with periodic lane closures scheduled during nighttime hours or outside of peak travel times as needed. Drivers can expect the following lane closures and upcoming impacts on northbound and southbound I-81:

  • From mid-February to mid-April, daytime right shoulder closures between 9 a.m. and 3 p.m., Monday through Thursday 
  • From mid-March until mid-June, nighttime right lane and shoulder closures between 8 p.m. and 6 a.m., Sunday through Thursday
  • From mid-May to mid-June, alternating left and right lane and shoulder closures during nighttime hours between 8 p.m. and 6 a.m., Sunday through Thursday 

The project also includes replacing six bridges, widening two bridges, installing approximately 2.6 miles of sound barrier walls along northbound I-81, improving the southbound exit 137 off-ramp intersection at Wildwood Road and adding interchange lighting at exits 137, 140 and 141 are also included in the project. Expected completion in early 2026.
